SUBJECT:
Grand River Slope Stabilization - Consultant Purchase Order
Extension
RECOMMENDATION:
That the purchase order #201645 to MTE Consulting Inc. be extended for the additional
amount of $50,860.00 plus applicable taxes for the Grand River Slope Stabilization
project.
BACKGROUND:
The Grand River Slope Stabilization project has been initiated to address slope stability and
erosion issues on the bank of the Grand River, near the Chicopee Vale subdivision. Both the toe
of the slope and the upper few metres of slope have experienced, and continue to experience
active erosion. The conditions identified as influencing the slope stability are groundwater
seepage onto the slope face, the discharge of surface water onto and over the slope area. This
has caused steepening and erosion of the upper slope and the toe of the slope at the edge of
the Grand River.
In February of 2010, the City retained MTE Consultants Inc. to complete an Environmental
Assessment (EA) Addendum, detailed design and contract administration for the Grand River
Slope Stabilization project. The approved fees for MTE Consultants Inc. were $266,958.00 plus
applicable taxes. On June 28, 2010, Council approved the EA for this project and directed staff
to implement its recommendations.
The project scope includes the installation of toe of slope protection, a groundwater collection
system, a surface drainage system, a reinforced slope stabilization system, and trail works.
On June 27, 2011, Council approved the tender to proceed with construction for $3,199,036.50
plus applicable taxes. The contractor started on August 15, 2011 and is expected to be
completed in August, 2012. Total costs for this project are estimated at approximately
$3,800,000 and were included in the 2011 capital forecast.
Throughout the duration of this project the City has consulted with several regulatory agencies
including the Grand River Conservation Authority (GRCA), Ministry of Natural Resources
(MNR), Ministry of the Environment (MOE), and Department of Fisheries and Oceans (DFO).

REPORT:
During the detailed design of the Grand River Slope Stabilization there have been changes to
the engineering consultant’s scope of work due to an increase in the construction schedule and
additional requests from regulatory agencies. MTE Consultants Inc. is requesting additional
fees due to a change in the original scope of work. The reason for changes to the scope of
work and associated costs are listed below:
Item Description Additional Cost
Additional work At the time the City hired MTE, it was not possible to $29,520
related to permits determine the extent of required permitting. In
particular the MNR Endangered Species Act (ESA)
permit. This is very involved and required several
meetings and application submissions. Due to the
length of time required to receive permit approval, it
was necessary to revise the permit to specify a two
year construction period instead of one.
Tender and Due to the unexpected duration of the ESA $9,740
Drawing Revisions permitting process and subsequent revisions to
address MNR comments, a complete resubmission
of the tender package was required. An addendum
was also required during the tendering process to
specify a two year construction period instead of
one.
Additional Working The project has been tendered with 105 working $11,600
Daysdays to complete the construction work compared to
70 working days of contract administration in the
consultant’s original scope of work. The additional
working days account for the complexity of
construction which was determined during detailed
design. A portion of the work does not require full
time inspection.
Total$50,860
FINANCIAL IMPLICATIONS:
Funding will be provided from the Grand River Slope Stabilization account. There is currently a
projected surplus in this account of approximately $1,588,000.
Total consultant engineering fees for Grand River Slope Stabilization are estimated to be 9.9%
of total construction cost.
Fee increases are based on consultant’s unit pricing submitted at the time of consultant
selection evaluation, and are therefore competitive in nature.
î ó î
CONCLUSION:
Staff have reviewed the request and recommend that the existing purchase order to MTE
Consultants Inc. be increased to complete the additional scope of work for this project.
